Lung tumors
Pulmonary Neoplasms
(Left) A 45-year-old male, asymptomatic, PA chest x-ray showing a right upper lobe nodule.
(Right) In the same patient, the upper lobe of the right lung is nodule, and the pleural depression, some solid components, and inflatable bronchograms may be seen. These manifestations are characteristic of invasive adenocarcinoma and resection biopsy is recommended.
(Left) 60-year-old female, hemoptysis. Chest x-ray shows a large mass in the upper lobe of the right lung, and due to its large size, primary lung cancer is highly suspected.
Axial CT (right) shows a large mass in the upper lobe of the right lung involving the anterior bronchi of the upper lobe of the right lung. Tumor-induced luminal involvement may lead to haemoptysis. Note the central emphysema surrounding lobular lobes.
(Left) Smoker, weight loss and hemoptysis, chest x-ray showing a reduction in the lower lobe of the right lung, secondary to a right hilar mass (curved arrow) horizontal fissure downshift (straight arrow).
(right) Axial CT shows complete atelectasis (straight arrow) in the lower lobe of the right lung, and loss of midlough volume secondary to central tumors leads to horizontal fissure (curved arrow) displacement. Diagnosis of small cell carcinoma by bronchoscopy.
(Left) Patient cough and hemoptysis, squamous cell carcinoma of the upper lobe of the left lung. PA chest x-ray shows consolidation of the upper lobe of the left lung with intrinsic cavities. Lung cancer may present as lung consolidation.
(Right) In the same patient, coronary CECT shows lesions as a large, uneven central necrotic cavitation-type mass that invades the mediastinum directly and causes occlusion of the posterior bronchial lumen of the upper lobe of the left lung.
(Left) 52-year-old smoker with advanced lung adenocarcinoma. PA chest x-ray shows enlargement of the upper lobe nodules of the right lung and ipsilateral right hilar and mediastinal lymph nodes.
(Right) In the same patient, lateral chest x-ray shows a local invasive tumor leading to locally increased density.
(left) In the same patient, axial CT shows irregular upper lobe nodules of the right lung, multiple enlarged lymph nodes in the right hilar and mediastinum, enveloping and narrowing of the lumen of the central tracheobronchus of the right lung, and thickening of the posterior wall of the right main bronchi.
(Right) Coronary CT of the same patient shows that the right tracheobronchial tree is enlarged in the mediastinum and hilar lymph nodes are embedded, and the lumen is narrowed.
In patients with (left) advanced lung cancer, axial CECT shows a large mass of the right hilar with an intraluminal tumor in the right main bronchi.
(Right) In the same patient, axial CECT shows a huge heterogeneous tumor that invades the mediastinum and superior vena cava (curved arrow). Central low density with peripheral strengthening suggests extensive central necrosis. Central lung cancer usually develops symptoms and can present as a hilar or peri-hilt mass.
(Left) Asymptomatic smokers, axial CT shows small nodules in the upper lobe of the right lung, and multifocal discontinuous pleural plaques consistent with previous exposure to asbestos. Smokers who are exposed to asbestos are at high risk of lung cancer.
In lung cancer patients (right), axial CT shows a lower lobe nodule of the left lung, and foliage, burr, and vacuole are all highly suspicious features of primary lung cancer.
In patients with (left) advanced lung cancer, axial CT shows a mass in the lower lobe of the left lung with irregular edges, and multiple nodular thickening of the left pleura consistent with pleural metastases.
(Right) Patients with multifocal adenocarcinoma confirmed by biopsy, multiple mixed ground glass foci in both lungs, irregular margins.
(Left) Patients with cervical cancer lung metastases, PA chest x-ray showing both lung nodules and masses and a right pleural effusion. Lesions are mostly located in the middle and lower parts of the lungs, consistent with the distribution of pulmonary circulation.
(Right) In a patient with a lung metastase with an unknown primary tumor, coronary CECT MIP images show multiple small nodules in both lungs, some of which are centrally distributed in blood vessels, consistent with hematogenous metastases.
(Left) Cancerous lymphangitis. The lobules of both lungs are thickened at intervals and the bronchial wall is thickened. Small lung nodules represent hematogenous metastases.
(Right) Hemoptysis patient, bronchoid carcinoid carcinoma. Axial CT shows a central spherically enlarged mass that results in atelectasis in the upper lobe of the right lung with bronchial obstruction causing mild dilation of the internal bronchial mucus filling.
(Left) 79-year-old male with cough and chest discomfort. PA chest x-ray shows consolidation of the upper lobe of the right lung with internal air bronchial signs and antibiotic therapy is ineffective.
In the same patient (right), axial NECT shows lump-like consolidation of the upper lobe of the right lung, burrs at the edges, and an internal air bronchial sign. CT-guided lung biopsy is diagnosed with primary large B-cell non-Hodgkin lymphoma. Lung lymphoma may present with air bronchial signs, similar to lung infections.
